Roughness in cycles render. Need help with nodes
First of all problem with the roughness raised because of the missing glossy map. To tell the truth, I don't have it :)
So if you created your maps as me in photoshop and applied it as texture (Normal; Diffuse and the main one)  always save it as tiff format (don't forget about compression when you save it). Other formats like png make less quality. Also, use RAW photos as donors of maps.
Second: if applied your hi-res texture on your object(without a glossy map) and after rendering you're found that the object looks dry ( For instance you rendered you brownie cake or donut) don't worry! You can solve this problem with MIXShader. After changes of your Principled BSDF Shade create the second one, Glossy Shader. Turn off the first one and adjust glossy shader. Then add Mixshader. Connect Glossy and Principled Shader to Mixshader and magic will happen.
In my case, I adjust bump and normal maps they blowing out my object reflectivity. It helps a lot but not as I want because of a problem with the texture source material.
Second I didn't use HDRI, therefore I add it.
Thanks to everyone who helped me!!
